The present invention will be further described in detail below with reference to the accompanying drawings. Embodiment 1:

2 is a schematic structural view of a coaxial adapter according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view of the coaxial adapter of FIG. 2. Referring to FIG. 2 and FIG. 3, the coaxial in this embodiment The adapter is composed of an outer conductor 21 and an inner conductor 24 disposed inside the outer conductor 21, wherein one end of the inner conductor 24 extends from the outer conductor 21 to be connected to a hard connector to be tested, and the other end and the outer conductor 21 The standard connector connector 22 provided at one end cooperates to form the inner core of the standard connector connector 22, and the standard connector connector 22 provided on the outer conductor 21 is used to cooperate with another hard connector to be tested. In the present embodiment, the inner conductor 24 can be fixed inside the outer conductor 21 by a supporting medium, and the inner conductor 24 can be fixed inside the outer conductor 21 by knurling and barb technology to prevent the inner conductor 24 from rolling, rotating, etc. inside the outer conductor 21.

It should be noted that the shape of the cross section of the outer conductor 21 may be selected according to a specific situation, such as a square shape, a circular shape, or the like. In this embodiment, the outer conductor 21 is selected to be a circular tube, and the inner conductor 24 is internally provided. It can also be selected according to the actual situation. The inner conductor 24 in this embodiment is selected as a cylindrical rod shape, and the inner conductor 24 extends from the portion 241 of the outer conductor 21 for mating with the hard connector, and the manner of the cooperation can be various. For example, the protruding portion 241 (i.e., the joint 241) may be a smooth cylindrical joint that is directly inserted into the hard connector to be engaged therewith. In order to ensure the reliability of the connection, the joint 241 in this embodiment may be provided with at least one groove and/or a boss that cooperates with the hard connector, so that the joint 241 and the hard connector are engaged with each other, and the outer conductor 21 is also The outer conductor of the hard connector is tightly coupled, so that the joint 241 of the embodiment is reliable in connection with the hard connector, and the RF signal can be stably transmitted, thereby ensuring the test effect.
